The Basics of Humidity & Comfort

Humidity significantly affects how comfortable you feel in your home, regardless of the actual temperature.

Understanding Humidity

Humidity is the amount of water vapor present in the air. Managing indoor humidity is essential for maintaining comfort and health within your living spaces. When humidity levels are high, the air can feel clammy and dense, which can make it difficult to breathe and cause discomfort even in cooler temperatures. High indoor humidity fosters the growth of mold and mildew, organisms that thrive in moist environments.

These can result in significant damage to your home and health problems, including respiratory issues and worsened allergy symptoms. Excess moisture can also attract pests like dust mites, which are known to exacerbate allergies and asthma. Therefore, controlling indoor humidity is crucial to prevent these problems and maintain a healthy, comfortable home environment.

How Humidity Affects Indoor Air Quality

High humidity levels directly reduce indoor air quality, fostering the growth of dust mites, mold, and mildew. These can degrade air quality and trigger respiratory problems and allergic reactions. Excessive moisture also damages indoor materials, causing wood to warp, paint to peel, and fixtures to corrode. This adds particulate matter to the air and further diminishes its quality.

Controlling humidity is a fundamental service provided by R.F. Ohl, aimed at preserving both the structural integrity of your home and its inhabitants’ health. By regulating moisture levels, R.F. Ohl helps ensure that indoor air remains clean, fresh, and healthy, providing a comfortable and safe environment for everyone.

Air Conditioning & Humidity Control

Here’s all you need to know about air conditioning and humidity control:

How Air Conditioners Work

Air Conditioner Condenser

Air conditioners use a refrigeration cycle involving evaporation, compression, condensation, and expansion to cool air. Warm indoor air passes over cold evaporator coils, losing heat and moisture. The refrigerant in the coils absorbs this heat, changing from liquid to gas, which is then compressed and heated further. 

After releasing the heat outside and condensing it back to liquid, it cools again via an expansion valve before returning to the evaporator. This cycle not only cools the air but also removes moisture by condensing it on the coils, effectively reducing indoor humidity and improving comfort.

Air Conditioner Components that are Critical to Humidity Removal

Air Conditioner Evaporator Coil

The evaporator coil is an important component in air conditioning, crucial for extracting heat and moisture from indoor air. As air passes over these cold coils, moisture condenses into droplets, which are then collected and removed, effectively reducing humidity and cooling the air. Properly sizing the air conditioning system is also vital for efficient humidity control. An undersized AC unit struggles on hot days, while an oversized cooling unit might cool too quickly without adequately removing humidity, creating a clammy feel. 

If you are due for an air conditioner replacement, R.F. Ohl ensures systems are properly sized by evaluating factors like room dimensions and local climate, optimizing dehumidification and comfort. Call now for a free consultation!

Enhancing Humidity Removal with Your Air Conditioner

Enhancing humidity removal with your air conditioner is important in maintaining a healthy and comfortable living space.

Optimal Settings for Humidity Control

Setting your thermostat correctly is crucial for effective humidity management. Ideally, keep the thermostat at a consistent 78 degrees Fahrenheit when you’re home and slightly higher when away. This consistency helps your air conditioner balance cooling and dehumidification without overexertion.

R.F. Ohl can further improve humidity control by installing programmable thermostats. These devices automatically adjust the temperature per your schedule, maintaining optimal humidity and comfort levels while optimizing energy use. This ensures a consistently comfortable environment and enhances the efficiency of your air conditioning system.

Signs Your AC Is Not Properly Controlling Humidity

If your air conditioner is not effectively controlling humidity, you might notice these signs:

  • Persistent Mustiness: Constant musty odors indicate high humidity levels uncontrolled by your AC.
  • Condensation on Windows: Water droplets inside windows show excessive indoor moisture.
  • Peeling Wallpaper or Paint: High humidity can lead to peeling wallpaper and blistering paint.
  • Warping Wood: High moisture levels can cause doors, floors, and woodwork to warp or swell.
  • Increased Allergen Presence: Elevated humidity promotes mold and dust mite growth, worsening allergies and asthma.

Recognizing whether these symptoms stem from a mechanical failure or an inadequately sized or outdated system is crucial in determining the right solution.

Mechanical issues might include problems with the AC’s compressor or a refrigerant leak, which need professional repairs. On the other hand, if your system frequently struggles to reduce humidity even when functioning correctly, it may be time to consider a system upgrade or adjustment.
